【问题描述】：
我正在尝试从 1 或 7 对我的用户进行排名。如果登录用户的排名为 7，请说“您是员工”。如果没有，请执行其他操作。但是，例如，如果我给用户 1 排名 7，则什么也不会发生。然后，如果我给用户 2 排名 7，两者都会收到消息说你是员工。
我已经为此苦苦挣扎了 3 天，但没有发现问题所在。我想让网站做的是找出登录用户是否排名第 7（如果有其他人，但只有登录的人排名第 7），如果我的数据库中的其他人排名第 7 而不是你，你不应该得到“你是员工”的信息。我有一个名为GamesNet 的数据库，一个名为members 的表，我的用户ID 名为memberID，还有一些其他列名为username、password、email 和Rank。
这是一个不错的设置，对吧？ 这是我的代码：
$stmt = $db->prepare('SELECT Rank, memberID from members where memberID');
$stmt->bindParam(7,$memberID, PDO::PARAM_INT);
$stmt->execute();
$result = $stmt->fetch(PDO::FETCH_ASSOC);
if($result['Rank'] == 7){
echo "You are a staff member.";
}else{
echo "Hello you are not a staff.";
}
?>

$stmt = $this->_db->prepare('SELECT password, username, memberID FROM members WHERE username = :username AND active="Yes" ');

}
